2.2. Laser Classification
Laser class 3B/lllb laser
The used laser is a
Class 3B/lllb components are unsafe for eye
exposure. Usually only ocular protection would
be required. Diffuse reflections are safe if viewed
for less than 10 seconds.
Labels reprinted here are examples relevant to
the laser classes. For detailed specifications
observe the label on your coplanarity laser.
2.3.
User Precautions & OEM Responsibilities
The specific user precautions as specified in IEC 60825-1 and FDA CFR Title 21 Part 1040 are:
Requirements
Remote interlock
Key control
Power-On delays
Beam attenuator
Emission indicator
Warning signs
Beam path
Specular reflection
Eye protection
Laser safety officer
Training
LMI Class 3B/lllb laser components do not incorporate the safety items in the table above. These items
are added and completed by Assembléon. Therefore the LMI Laser Sensor should not be operated
outside the machine.
2.3.1. Remote Interlock
A remote interlock connection must be present in Class IIIB laser systems. This permits remote
switches to be attached in serial with the key lock switch on the controls. The deactivation of any remote
switches must prevent power from being supplied to any lasers.
In the AX-201 with coplanarity checker this is covered by the separate E-stop circuit for the laser. The
'AX-201 Enabling switch' will not enable the Laser. For detailed information see chapter 3.2.2 Electrical
Diagram
2.3.2. Key Control
A key operated master control to the lasers that prevents any power from being supplied to the lasers
while in the OFF position. The key can be removable in the OFF position but the switch must not allow
the key to be removed from the lock while in the ON position.
In the AX-201 with coplanarity checker the Machine Mains switch with pad-lock does not allow any
power being supplied to the laser. For information on use of the Mains switch with a padlock see
chapter H7 Maintenance 1st 'NOTE'
